4 Claims. i

This invention relates to electric fencing and more particularly'to aninsulated bracket used in connection therewith,

The principal object of the invention is the provision of an insulatedcorner bracket for electric fencing.

A further object of the invention is the provision of an insulatedcorner bracket incorporating means for holding a fence wire in stretchedposi tion.

A still further object of the invention is the provision of an insulatedbracket for electrical fencing incorporating means facilitating themounting of a bracket on steel or wooden posts.

A still further object of the invention is the provision of a method ofinstalling an electrical fence including stretching the fence overrotatable insulators and holding each straight section of fence instretched position while subsequent sections thereof are installed.

The electrical fence insulator shown and described herein has beendesigned to facilitate the construction of single wire electric fenceswhich are commonly employed for fencing in live stock. The principalnovelty in the invention resides in the formation and construction ofthe insulated bracket which construction enables it to be used to hold astretched section of fence while subsequent sections thereof areerected.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed with- .out departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawing, wherein-Figure 1 is a side elevation of the insulating bracket.

Figure 2 is a cross sectional side elevation of the insulated bracket.

Figure 3 is an end elevation of the insulated bracket illustrated inFigure 1. Lines 22 on Figure 3 indicate the cross section illustrated inFigure 2.

Figure 4 is a top plan view of a section of fencing illustrating the useof two of the insulated corner brackets shown in Figures 1, 2 and 3.

Figure 5 is an enlarged end elevation of one of the insulated cornerbrackets illustrated in Figure 4 and shows a modification in the bracketattachment means.

Figure 6 is a front elevation of a bracket carrying an insulatorrotatably mounted thereon for use in connection with the insulatedcorner bracket shown in Figures 1, 2, 3, 4 and 5.

Figure '7 is a cross sectional side elevation taken on lines l-'! ofFigure 6.

By referring to Figures 1, 2 and 3 of the drawings it will be observedthat an insulated corner bracket has been disclosed which consists of apair of flanged base members I!) and H which support in pivotal relationthereto an inverted Ushaped body member I2. The body member i2 ispivotally affixed to the pair of flanged base members it and II bysuitable means such as a bolt and nut assembly [3 as shown or a cotterkey (not shown). The end portions of the U- shaped body member l2 arerounded, as indicated at E4, to provide for the partial rotation of thebody member [2 about the pivot l3. Each of the flanged base members [0and H are provided with punched openings [5 and i6, respectively, andraised loops I1 and I8, respectively, one or both of which are used inattaching the insulated bracket to a supporting means such as a fencepost. The punched openings l5 and it provide for the insertion of a nailor screw and the loops I1 and I 8 provide for the passing of a wiretherethrough so that the device may be wired to a metal post, TheU-shaped body member H has an insulator I9 positioned in a rotatablemanner, as by means of a bolt and nut assembly 20, the insulator l9being circular in shape and having a deep annular groove formed in theperiphery thereof, as indicated by the numeral 2| in Figure 3. The boltand nut assembly l3 which forms the pivot between the body member l2 andthe flanged base members It and H has an arm 22 attached thereto bymeans of an eye formed in one end thereof, the arm 22 being positionedbetween the arms of the body member [2. The outermost end of the arm 2?.is provided with a pair of upturned brackets 23 which define a channeltherebetween lying on the central axis of the device and particularly inline with the deep annular groove 21 in the periphery of the circularinsulator l9 thereof.

By referring now to Figures 4 and 5 of the drawings the manner of usingthe insulated corner bracket will be seen. In Figure 4 a section offencing utilizing a barbed wire 24 is illustrated as positioned betweena pair of corner posts 25 and 26, respectively, and a line post 21. The

insulated corner brackets are shown attached to the posts 25 and 26 bymeans of nails and the arm 22 of the bracket attached to the post 25 isshown holding the barbed wire 24 in stretched position as the brackets23 on the arms 22 have been moved into position adjacent one of thebarbs of the barbed wire 24 so that the stretched wire 24 is directlysupported by the arms 22 and the bolt and nut assembly 13 which inturnis carried bythe flanged base members it! and II. The barbed wire ispassedthrough the device in the area between the insulator I9 and thearms 22. An arrow in Figure 4 indicates the direction of installation ofthe fence and by referring to, the other corner post 26, as illustratedin Elgure 4, the completely stretched and installed section of thefencing may be seen to pass through the insulated corner bracketattached to the post 26 and it will be observed that the arm 22 has beendisengaged from the barbed wire 24 so that the wire is supportedentirely-on the insulator l9. It will thus be obvious that the arm 22 isused only during the construction of the fence I to hold each sectionofthe fence-in stretched positionas itis being erected and thatimmediatelyafter the erection is completed thearms 22' are disengagedfrom the fence so that they will not cause a short when the electricalcircuit is established through the wire 24.

By referring now to Figure of the drawingan enlarged detail view of theuse of the insulated corner bracket is illustrated it being observedthat the brackets 23 on the arms '22 of the device engage the wire 23 bymeansof the barb formed thereon and thus serve to holdit. In Figure 5the alternate method of attachment of the insulated corner bracket hasbeen illustrated and attachment wires 28 and 29 are shown positionedthrough the loops IT and I8, respectively, of the flanged base membersit and I l, respectively, and

passed about a metal post'30.

In Figures 4, 6 and 7 a rotatable insulated bracket has been illustratedand is'used' in connection with supporting straight sections of fencingformed with the insulated corner brackets heretofore described; -Byreferring to Figures 6 and 7 these rotatably positioned insulatedbrackets may be seen to comprise a circular insulator 3| having a deepannular groove 32 formed in the periphery thereof, the insulator beingsupported on a base member 33 by means of at rivet or other suitablefastener 31 and the base 33 being provided with loops 35 and punchedopenings 35'so that it maybe attached to either a wooden or metal postbyeither nails or wires as heretofore described in connection with theinsulated. corner. bracket. The rotatable insulated bracket enables theinsulated corner brackets to be used in stretching the fencing wire.

It will thus be seenthat a simple and efficient insulated bracketihasbeen disclosed which may be advantageously" used in forming electricalfences and that the bracket not only supports and positions the fencewire with respect to supporting posts but maybe used to holdthefencingwire in stretched position during the installation thereof;
